At some point during Australian production the casting "CF" at the top of the rear of the block, next to the oil pressure sensor outlet was changed to "GF" for "Geelong Ford" plant. Also at some point late during production in an attempt to reduce the Cleveland tendency to overheat, a "pillow" block was produced to increase water capacity around the cylinders. | At some point during Australian production the casting "CF" at the top of the rear of the block, next to the oil pressure sensor outlet was changed to "GF" for "Geelong Ford" plant.

| − | A " | + | A "NASCAR" block was produced by Ford Australia (exact year unknown) for the US market. Exact numbers shipped to the USA is unknown. These "NASCAR" blocks were to have thicker cylinder walls and "better grade" cast iron, but due to bad core shift were no better than standard blocks. However it is known that most of these blocks were returned to Australia and used in regular production to clear the supply of blocks. |
Australian blocks have a "cast in" thermostat bypass plate, not stamped steel type. | Australian blocks have a "cast in" thermostat bypass plate, not stamped steel type. | ||

| + | Australian-built Cleveland engines used either a cast iron 2bbl or 4bbl manifold with 2bbl size ports. Initially the 302C was only available with a 2bbl carb (1974-'76) and the 351C had either a 2bbl or 4bbl option. | ||
Rochester carburetors were used on the 2bbls with an aluminum adapter plates. Carter Thermoquads were used on 4bbl spread bore-type manifolds with an aluminum EGR plate. Early production 4bbl manifolds had large secondary inlet ports. Later production 4bbl manifolds had the secondary ports reduced in size in an effort to increase mileage and throttle response particularly on 302's with the 4bbl option. | Rochester carburetors were used on the 2bbls with an aluminum adapter plates.

Early Australian production 302C's 1973-1975 (XA-XB Falcon) used US blocks with Aussie heads and crankshaft/conrods. Then it appears that US-built "C" blocks bought by Ford Australia were used up to the late '70's in regular production. |

Rated power (SAE net) was 115-122 hp (86-91 kW), depending on year and application. Cylinder heads used smaller combustion chambers and smaller valves and the intake ports were ovals whereas the others were rectangular. The only externally visible cue was the use of an open runner intake manifold with a stamped steel lifter valley cover attached to its underside, giving the appearance of previous generation engines, such as the Y-Block and the MEL. It was optional in Fox chassis cars including the Mustang and corporate cousin Mercury Capri, Thunderbird, Fairmont, and standard equipment in the Ford LTD. Poorly received thanks to its dismal performance and mediocre fuel economy, it was dropped after the 1982 model year, and is considered one of the worst modern Ford engines. |
